Downside: spreading it to others easier.
Vitamin D deficiency is a major factor in who gets a severe case. You know many humans have this? In America, I am pretty sure it is a majority. So most people are susceptible just off that. Then what of obesity? Lack of fitness? Zinc deficiency, and other nutrients, etc. A covid case for many people is a brain and lung damage sentence at minimum. All for the upside of I don’t want to be told what to do?
This is such a ridiculous American mentality I honestly wish for the end of the aberrant phenomenon of our social dominance, God save us.
